Loop Telecom | Voice & Data Multiplexers

Loop Telecommunication International, Inc., is a global-market oriented company supported by strong R&D, manufacturing, quality control, and service staff. The entire company is dedicated to providing Voice and Data communications access equipment and services that are applicable world-wide to all segments of the IP (Internet provider) market as well as narrow- band and wide-band data/voice markets
E-1500 CSU/DSU SERIES
The Loop-E 1500 CSU/DSU series provides an economic solution to E1 network access cost, when only a partial of 31 DS0 channels is needed. Clear channel (32 DS0 channels) is also available. The products support HDB3 (High Density Bipolar 3) coding and provide continuous error checking, performance polling, and in-service diagnostics. CPE interface include E1 CSU, serial DTE, Co-directional DTE, and router. With DTE port operating from 56 Kbps to 2048 Kbps, Loop-E 1500 CSU/DSU allows users to interconnect LANs and WANs, CAD and CAM, video conference, mainframe hosts etc. The router interface allows for LAN to WAN connection directly.
V4100 Universal Multi-service Access Platform
Designed for STM1 and DS3 networks, V4100 provides 504 Mbps cross-connect backplance capacity. Full STM1, OC-3 access, and OC-3 Add-drop. V4100 has full DS0 cross-connect built inside. The A-Mu conversion is also supported. The OC3/STM-1 port may be connected to OC3/STM-1 networks or to Loop-V 4200-28 with OC3/STM-1 port. Three DS3 ports can be connected to DS3 networks or Loop-V 4200-28 with DS3 port. Local control and diagnostics are supported via VT100 terminal connected to the console port, also Ethernet, Telnet, and SNMP is supported for control and diagnoses from remote locations.
V4200-9 & 28 Multi-Service Access Platform
The Loop-V4200-28 IMAP series is available in two kinds of shelf: Loop-V 4200-28, which is ANSI standard with connectors front and back, and Loop-V 4200-28ET, which is ETSI standard with all connectors access via the front. The Loop-V 4200-28 offers 3 high and 28 low speed slots. He V4200-28ET supports STM1 1+1 protection function, 1:6 T1/E1 interface card protection or 1:6 line protection function. The system can be configured as an:
• OC3 (STM1/STS3) access device, T1/E1 CSU/DSU with drop/insert & voice
• E1 to T1 converter (N x64)
• Digital cross-connect system (DACS)
• CSU/DSU, data from V.35 or X.21 port occupies a fraction of an E1/T1 port
• E1/T1 converter, A to Mu law coding and signaling handled.
V4200 IMAP OC3/STM1 plug-in card
The OC3/STM1 plug-in card provides OC3/STM1 access for the V4200-28. 1 to 1 protection is obtained when two cards are used. V4200-28 IMAP provides access for 1/3 of the OC3 capacity, so three 4200-28 systems will provide full OC3 access. Multicolor LEDs provide status indication for power/standby, LOS, LOF and test. Internal firmware, stored in flash memory, allows firmware to be downloaded. The Loop-V 4200 series offers local control and diagnostics via VT-100 terminal and also supports Ethernet, Telnet, and SNMP.
